The questions are standardized questions written by NBME, but your test won't be exactly the same as another schools. NBME will provide schools a pool of standardized questions, but each school picks which specific questions out of that pool to use. In other words, let's say NBME sends a pool of 500 standardized questions to School A and School B, but School A picks 100 questions from that pool that are different than the questions from the pool that School B chooses to use. The results between the 2 schools can't really be directly compared, but NBME sends specific standardized data in regards to each question. For instance, with the questions my school selected for our Neuro final from the pool of NBME questions, standardized results for each question added up to where a student whose performance was in line with the national average on those specific questions would score a 78%. But using different questions, a score in line with the standardized average might be higher or lower. You're not going to be able to compare school-versus-school unless it's 2 schools who chose the exact same questions, but you can compare school-versus-national average for the questions chosen by that school.
